Page 46: System Sequence Of Events Recording (Soe)
2.6 SYSTEM SEQUENCE OF EVENTS RECORDING (SOE) The GARD 8000 is supplied with a Sequence of Events Recorder (SOE). Up to 512 events are recorded, and time stamped with a 1 ms resolution.
Page 47: Teleprotection System
The GARD 8000 System is customized to provide the number of channels, type and number of channel interfaces, inputs and outputs and redundancy to meet your application needs.
Page 48: Distance Protection Termina L
The Distance Protection Module is a full featured protection terminal. It can be used as a stand-alone non-pilot or pilot distance protection system, or can operate in parallel with the GARD 8000 Current Differential Protection Module providing an independent and different measuring principle.

Distance Protection Manual. 2.10 CURRENT DIFFERENTIAL PROTECTION A Current Differential Protection Module can be integrated in the GARD 8000 System. Using one 64 kbps channel, the current differential relay can use the same communication link as the teleprotection system module, or it can have its separate channel interface.
Page 50: Aux Comm Unications Channel
Applications 2.12 AUX COMMUNICATIONS CHANNEL Two GARD 8000 Systems can be configured as shown in Figure 2-11, where two units communicate using a T1/E1 link. The typical application shows an RFL 9300 at each remote end. Each 9300 is connected to the GARD 8000 using a 64kb/s co-directional link employing a G.703 comms module.

If your GARD 8000 is equipped with Fiber Optic Modules, fiber optic connectors must be connected to the fiber optic heads on the rear panel of the GARD 8000. Type ST series bayonet fiber optic connectors (or their equivalent) are used with both singlemode and multimode fibers. The exact mating connector used will depend upon the head that is installed in the fiber optic module, and the specific optic cable being used.

Installation and Commissioning 4.6.3.1.2 OUTPUT POWER The GARD 8000 PLC transmitter is specified to provide 10W into a 50 ohm load. Adjustments to the output power are made with a 50 ohm dummy load connected. Any additional devices in the transmit path, such as hybrids, will reduce the effective output power.
Page 111 Installation and Commissioning 4.6.3.1.3 OUTPUT IMPEDANCE Once the GARD 8000 PLC has been connected to the line the output impedance should be adjusted to match that of the actual line. Impedance mismatches can cause signal reflections and other undesirable effects. The GARD 8000 PLC Power Amplifier provides an output impedance adjustment to accommodate small variations in actual line conditions.
Page 112 If this is a 2W system, perform the following Hybrid Tuning Procedure. The purpose of tuning the hybrid is to match the impedance of the GARD 8000 PLC system to the transmission line, thereby minimizing reflected power. Refer to Figure 4-16.

An additional set of backup protection algorithms are available when inter-relay communications are lost for any reason. The GARD 8000 Current Differential Module can be configured for optional single-pole tripping. The standard ordering version is for three-pole tripping only. Three terminal configuration is also available as an option.
Page 497: Configuration
13.2.1 SYSTEM CONFIGURATION OVERVIEW The GARD 8000 System differs from most conventional multifunctional differential relays in that rather than supplied with very complex generic default logic, the GARD 8000 can be easily customized to meet your specific application requirements. For most applications, the factory default logic may be suitable but RFL will modify it free-of-charge when required.
Page 498: Figure 13-1 Location Of Front Panel Leds
NOTE While most of the GARD 8000 Modules can be installed and removed while powered, it is not recommended to do so while Tripping Circuits are enabled as unintended operations may result.

System Logic. 13.5.2.9 RECLOSER BLOCKING FUNCTION The GARD 8000 provides a recloser blocking output. The logic is shown in Figure 13-48. This logic is implemented in the programmable logic processing of the controller module. The recloser block function is enabled for a period of 3 seconds after the first trip signal is generated by one of the phases.
